[sdiy] strange sequencer behavior

[Sven Windisch]

hi.

i got some strange behavior from my sequencer last days. i added a feature
shown in [0]. the 4024 counter and the 74hc85 comparator. this way i'm
able to encode the length of the sequence as a binary word. i.e. if i set
the switches to 0100 the sequence resets after the 4th stage. this works
well for slow speed. but if i tune the speed up it does the following: it
counts 1, 2, 3, 4, as it should do, then leaves out 5 and 6 (and somtimes
7) and ounts on from 7 (or 8) through 16. this occurs only at a higher
speed, if i slow it down again it works as it should do.

any hints?

greetings, sven.
